Bitcoin Research Kit
"Shout out to Bitcoin Research Kit and researchbitcoin.net. Two data sources for On-Chain Data. Couldn't recommend them highly enough." — James Check (CheckOnChain), What Bitcoin Did #1000
Open-source on-chain analytics for Bitcoin. Combines functionality of Glassnode (on-chain metrics), mempool.space (block explorer), and electrs (address index) into a single self-hostable package. Runs entirely off a Bitcoin node, no exchange feeds or external APIs required. Bitview is a hosted instance of BRK.
Data
Blockchain — Blocks, transactions, addresses, UTXOs.
Metrics — Supply distributions, holder cohorts, network activity, fee markets, mining, and market indicators (realized cap, MVRV, SOPR, NVT).
Indexes — Date, height, halving epoch, address type, UTXO age.
Mempool — Fee estimation, projected blocks, unconfirmed transactions.
Usage
Website
Browse metrics and charts visually. Use it free at Bitview, no signup required.
API
Query thousands of metrics and blockchain data in JSON or CSV. Freely accessible at Bitview.
Documentation · JavaScript · Python · Rust · LLM-friendly schema
Self-host
Run your own website and API. Private, verifiable, self-sovereign. Runs alongside Bitcoin Core.
Library
Build custom applications in Rust. Use the full stack or individual components (parser, indexer, computer, server).
